Highway construction is the main artery of economic development in our region. In the past five years, the total investment in transportation fixed assets in the whole region was about 45 billion yuan, exceeding the total investment from Xinjiang's liberation to 2003. This year, the planned investment in highway construction in our region is 654.38+0.5 billion yuan, which is the year with the largest investment and the largest number of construction projects in the history of highway construction in our region. In such an economic investment environment, highway engineering bidding, as an important medium of engineering commodity trading activities, generally consists of three parts: bidding quotation, construction organization design and comprehensive information. In bid evaluation, quotation usually accounts for 40% ~ 60% of the bid score; Construction organization design accounts for 20% ~ 50% of the tender score; Comprehensive information accounts for 10%~20% of the bidding score. As can be seen from the above ratio, the bidding construction organization design is an important part of bidding.
1 the position and function of bidding construction organization design in bidding
1. 1 The construction organization design of highway engineering bidding is the concrete embodiment of the contractor's management ability, construction organization concept and construction technical level.
This is the contractor's investigation and analysis of the characteristics, natural conditions and external environment of the bidding project, combined with his own technical level, management ability, construction experience, technical equipment, project development concept and bidding decision-making thinking, through the formulation and comparison of the construction plan of the bidding project, the allocation of production factors and the formulation of various technical guarantee measures; Comprehensively and systematically evaluate the technical feasibility of the implementation project and the conformity of the construction conditions; On the other hand, the bidding construction organization design is also a scientific, reasonable and systematic arrangement made by the contractor for winning the bid according to the requirements and regulations of the owner's bidding documents.
1.2 highway engineering bidding construction organization design is the carrier of the contractor's technical superiority and innovation.
The bidding construction organization design is a comprehensive reflection of the contractor's technical strength and project management ability, and also a reflection of the contractor's concern for the project owner and his understanding of the owner's bidding documents. General contractors will show their patented technology, professional technology, technical advantages and technological innovation ability to the owners in this "window"-bidding construction organization design.
1.3 the function and influence of the construction organization design of highway engineering bidding on bidding quotation.
In the process of compiling the tender, the tender offer is compiled by the contractor according to the requirements stipulated in the tender documents and in combination with the highway engineering construction quota, charging standard, material price and expected profit determined by the enterprise's competitive strategy. Whether it is reasonable or not depends on a scientific, advanced and feasible bidding construction organization design. In the bidding construction organization design, such as the project and quantity of large temporary facilities and transitional projects; Construction layout, floor space, service life, material storage location, supply mode, transportation mode and distance, earthwork allocation scheme, supporting mode of construction machinery, etc. The details and omissions considered in the scheme will have an important impact on the quotation, especially whether the construction scheme is scientific and reasonable, which will directly affect the correctness of the tender quotation.
1.4 highway engineering bidding construction organization design is the basis to reflect the contractor's comprehensive ability.
By organizing the bidding construction design, the owner can first investigate the influence of the contractor on the requirements put forward in the bidding documents, such as the requirements for compilation depth, construction progress and quality. Secondly, inspect the contractor's construction technology and management level, such as the advanced level of construction technology, innovation level, construction organization level, quality, safety, construction period, environmental protection ability, etc.
1.5 highway engineering bidding construction organization design is the guarantee of competitiveness and the basis of guiding contract negotiation.
With the continuous improvement of the bidding mechanism, more and more owners have adopted a new bid evaluation method-secondary bid evaluation, that is, the technical bid (bidding construction organization design) is evaluated first, and then the commercial bid is evaluated. When judging, the score of the former may be as high as 50% ~ 70%; Therefore, high-quality bidding construction organization design is the guarantee of the contractor's competitiveness in the engineering market. Since 200 1 China joined the WTO, many practices in the field of engineering construction have been in line with international practices. Before winning the bid, the owner will review the rationality, advancement and feasibility of the bidding construction organization design, and ask the contractor questions about related issues and ask the contractor to explain or clarify. This practice is usually called technical negotiation internationally. Whether it is technical negotiation or economic negotiation, the focus of discussion between the two parties to the contract is still the specific construction scheme, construction organization, technical measures, quality assurance measures, price composition and so on. The basis for guiding the contractor to conduct the above negotiations is the corresponding content in the bidding construction organization design.
2 characteristics of highway engineering bidding construction organization design
2. 1 compilation time is hasty.
According to Article 24 of the Bidding Law of People's Republic of China (PRC), "the tenderer shall determine the reasonable time required for the bidder to prepare the bidding documents; However, the project that must be subject to tender according to law shall not be less than 20 days from the date when the tender documents are issued to the deadline when the bidders submit their tender documents. " Article 27 of the Measures for the Administration of Tendering and Bidding for Highway Engineering Construction stipulates that "the time from the issuance of bidding documents to the bid opening shall be determined by the tendering unit according to the project scale and bidding content, and the time for large and medium-sized projects shall generally not exceed three months". However, in addition to attending the pre-bid meeting organized by the owner and inspecting the construction site, the contractor usually spends more than two weeks, not more than three months. Contractors often don't have enough time to conduct detailed construction project investigation and prepare relevant materials.
2.2 The uncertainty of compilation basis.
The direct basis for compiling the bidding construction organization design is: bidding documents, design documents (including drawings and reference materials), answering questions, addendum books, engineering construction standards, construction specifications, acceptance specifications and regulations of relevant departments. These are provided and known by the owner. In addition, there are special requirements of the owner (express or implied), project environment, engineering construction conditions, the best construction period required by the owner, etc. The compilation depth of the design documents provided by the owner does not match the requirements of the bidding documents, which is uncertain. For these uncertain foundations, contractors need to rely on rich experience, collective wisdom and courage to accept the test of the market.
2.3 the uncertainty of the content and depth of compilation.
The bidding documents of different owners have different requirements on the content and depth of bidding construction organization design. For example, in the bidding of expressway projects, most owners explicitly require contractors to write according to the template requirements in the bidding documents of the Ministry of Communications, and the content and depth of the requirements are clear; Because there is no unified industry model at present, the requirements of different owners are quite different, which requires contractors to be good at accumulating and collecting bid evaluation information from different owners, so as to analyze and make correct judgments according to the characteristics of the project and meet the requirements of the owners to the greatest extent.
2.4 Scalability of compiled content.
Because the bidding construction organization design is a principled, programmatic and instructive document, it covers a wide range of contents and has expansibility. Compared with the implementation of construction organization design, it is similar to engineering projects, compilation basis, methods and contents. After winning the bid, the implementation construction organization design will be compiled, and it will be refined and expanded on the basis of the bidding construction organization design. For small or single projects, it can be refined directly according to the requirements of quality standards and specifications, and compiled into construction management documents such as quality plans.

4 highway engineering bidding construction organization design points
4. 1 Read the tender documents carefully to meet and respond to the tender requirements. By reading and analyzing the bidding documents, we can understand the basic requirements of the owner for the construction period, quality and safety of the whole project, and master the possible express and implied contents. Master the number of projects, site distribution, building types, construction difficulties, difficulties and key projects. Combined with engineering practice, strictly meet the requirements of bidding documents and avoid wasting bidding documents. 4.2 Pay attention to on-site inspection and bidding answering questions.
On-the-spot investigation and bidding answering questions are an important work content in the bidding process. Through on-site investigation and bidding, we can understand and master the engineering characteristics, natural characteristics, construction conditions and market conditions of production factors, truly grasp the owner's relevant intentions, find out the difficult problems, and grasp the main contradictions, so as to make the preparation of bidding construction organization design more practical, more targeted and feasible, and closely combine the engineering characteristics, on-site actual conditions and owner's requirements.
